OMG, you two are amazing! 'Cognac coloured diamonds'... oh my! Guess what? I'm having 5 days off work and this morning I went downtown for jewellery shopping - I'm already broke. Should never visit this section again, when I log in here...
Anyway, I bought white pearls embroidered on a red lacey ribbon. A necklace that is. Really pretty.

The Moroccan wedding tiaras aren't "fabulous royal heirlooms" as each parure is bought direct from the jeweller.
The tiaras of the present King's sisters reflect a Moroccan/Islamic/Occidental style, not a Western one.

I think this poster meant Moroccan/Islamic/Oriental. Occidental means Western. It is the opposite of Eastern.

I wanted to comment on little Khadija's tiara. In some countries little girls that have memorized or started to memorize the Koran receive a tiara. I know she is a just a little girl but I have seen children that age memorize the Koran. And I have seen ceremonies where they are given tiaras(not of fine quality like royals would have or anyting) to celebrate this. It's a beautiful thing to see the ceremony at the end of a Koran memorization class. I'm not saying this is the reason she has a tiara but just throwing it out here as a possibiliy.
